CARPENTERS PLANE.

SPECIFICATION forming part of Letters Patent No. 444,897, dated January 20, 1891.

Application filed April 5 1889. Serial No. 306,093. (No model.)

To all whom it may concern:

Be it known that I, OLIVER LoNevAL, of Millbury, in the county of lVorcester and State of Massachusetts, have invented certain new and useful Improvements in Carpenters Planes; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, forming a part of this speciiication, and in which- Figure l represents a side view, partly in section,of a carpenters plane embodying my improvements. Fig. 2 is ahorizontal section through the handle, showing a plan of the plane with all the old detachable parts removed to more fully illustrate my improvement. Fig. 3 is a plan of t-he bottom of the plane. Fig. a is a central vertical longitudinal section through the parts shown in Fig. 2, and Fig. 5 is an enlarged view showing a vertical section through a part of the planebed.

My invention relates more particularly to metal planes, but is also applicable to other styles of planes; and it consists in'combining with the plane-bed oiling devices for supplying the bottom thereof with a proper amount of oil or other lubricating material to render the operation of planing more easy to perform, `as hereinafter more fully set forth.

. it will be unnecessary to give a detailed description of said old parts.

I accomplish the desired result-wiz., of

oiling the bottom of the plane and the sur-` face of the stock operated upon-by combining an oil-receptacle II with the bed of said plane back of the knife and other detachable parts connected therewith, and by converting the usual front handle into an oil-receptacle, the same being made hollow for the purpose, as is shown in Fig. et. The oil is allowed to pass out of said receptacles for the above purpose through suitable openings a, made in the planedoed A. The receptacles are filled with cotton waste or other suitable material saturated with oil, as is'cornmon in other oil-receptacles, and consist of the inverted detachable cups de, which are provided with suitable plugged inlets d e for supplying the oil thereto, and having the screws b passed vertically through the same into the bed A for holding them in position.

The detachable cups d e of the oil-cups are made oil as well as air tight where they connect with the plane-bed, aswell as where the holding-screws b thereof pass through, by means of suitable elastic Washers or packings c. The motion of the plane over the surface being operated upon produces just suiiticient suction to draw out the required amount of oil to produce the desired result, and the discharge thereof is facilitated by making the discharge-openings tunnel-shaped or flaring upward, as is best shown in Fig. 5. Said form of openings also obviates the liability to their becoming clogged or stopped by dust and other particles entering and becoming lodged therein. As above constructed, such particles, if they enter, are allowed to pass up and spread out into the oil, and therefore do not materially interrupt the outflow of said oil. Although it is preferable in practice to thus form the openings a, I do not limit myself thereto, but reserve the right to employ such shapes as are suitable for the purpose.

I am aware of the United States Patents to XV. Vood, No. 191,393, dated Hay29,1877; E. F. Gordon, No. 213,1011, dated March 1l, 1879, and to L. A. Dearth, No. 363,213, dated May 17, 1387, and make no claim to any of the constructions therein set forth.

Having now fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, ism

IOO

In a oarpenters plane, the combination, with the plane-bed A, having a series of vertical openings a therein, of detachable oups d and e, having suitable plugged inlets d e and tted over said openings a in the bed, the fastening-screws b, passed vertically through the oil-receptacles into the bed,l the absorbent material contained Within the oil-receptacles, and the paokings c, interposed between the under side of the heads of the fastening- 1o screws and the oil-receptacles and between said oil-receptacles and the top of the bed, substantially as and for the purpose set forth.

OLIVER LONGVAL.
